目的:考察从五味子科分离到的30种木脂素的体外抗氧化活性,筛选出具有较强抗氧化活性的化合物。方法:通过总抗氧化能力和DPPH自由基清除能力,对30种木脂素进行抗氧化活性测试。结果:(+)-安五脂素、内消旋二氢愈创木脂酸和五味子酯甲表现出较强抗氧化活性。结论:本文研究了五味子中木脂素类的抗氧化活性,为五味子科植物的研究开发提供参考。
OBJECTIVE: To investigate the in vitro antioxidant activities of 30 lignans isolated from Schisandra, and to screen out compounds with strong antioxidant activity. Methods: Antioxidant activity of 30 lignans was tested by total antioxidant capacity and DPPH free radical scavenging activity. Results: The (+) - pentaconitine, meso dihydroguonic acid and Schisandra ester A showed strong antioxidative activity. Conclusion: The antioxidant activity of lignans in Schisandra chinensis was studied in this paper, which provides references for the research and development of Schisandra chinensis plants.
